Subject: [PATCH] Add script to deploy into a single node minikube instance

This script takes an existing minikube instance in which it creates a
block device image under mnt/vda1/heketi-bricks.img that is connected
to /dev/loop1.  Then gk-deploy is started in the single-node mode on
top of minikube and a default storage class gluster-storage is
created.
